When an influential person (including you) (authority Twitter User) tweets your link, it is a sign to the search engines that it’s good, trusted content.

This point gains significance when viewed in light of the previous point. Both Google and Bing denied knowing the identity of individuals, but Bing did confirm that public figures and companies could be identified as authoritative sources.

Google assigns Twitter accounts a score. The more authoritative the Tweeter is, the higher their score. Therefore, if a highly ranked Tweeter links to your site, a trickledown effect will rank your site slightly higher. The age of your Twitter account and how authoritative you are affects your score, and ultimately your ranking, in the eyes of Google.

Retweets also help the search engine understand that the blog or article in question is a trusted source of information, which results in higher rankings. So, the more people who re-tweet your original link, the higher your site might climb in a Google search index.

If an authoritative person – potentially, that means you – tweets your link, Google views it as a trusted source of information. So get your information out there by posting Tweets!
